The Cook Islands police commissioner, Ma'ara Tetava, says a drugs bust that has resulted in 13 people being charged is the culmination of a year-long investigation.
The 13 are being held in custody until their first court appearance later this week.
So far they've been charged with 55 drug-related offences and Mr Tetava says some of the group will also face corruption charges.
Mr Tetava says the arrests have been a year in the making and during that time he's worked closely with a team of New Zealand police.
"Because of the sensitivity of the investigation and the people suspected of being involved, I sought the assistance of the New Zealand police, through the Commissioner of New Zealand Police, to help me on this one, which they did."
